Application filed June 21,1890. Serial No. 356,243. (No model.) Y

To a/ZZ whom, t 721,601/ con/cern:

Be it known that we, WILLIAM H. BARNUM, of Danbury, in the count-y of Fairfield and State of Connecticut, and EDWIN C. OAKLEY, of Bethel, in the county 0I" Fairfield and State of Connecticut, have invented a certain new and useful Improvement in Hat-Trimming Machines, of which the following is a specilication.

Ourimprovement relates to machines which are employed for trimming thebrims of hats. These machines are commonly termed roundingfjacks or hat-trimming machines.

We will describe a machine embodying our improvement, and then point out the novel features in the claims.

In the accompanying` dra-wings, Figure l is a sectional elevation of a machine embodying our improvement. Fig. 2 is a sectional elevation of the upper portion of the same on a larger scale, the section being taken as indicated bythe dotted line a: Fig. 3, and representing certain parts in different positions. Fig. 3 is a horizontal section of the machine,

taken at the plane of the dotted line y y, Fig.`

l. Fig. is a vertical section taken at the plane of the dotted line .a e, Fig. l, and looking in the direction indicated by the arrow,

whichis marked at one end of said line. Fig. 5 is a vertical section, on a large scale,of the cutters and their appurtenances, besides certain adjacent portions of the machine. Fig. G is a top view of a hold-down or device for retaining the parts in position while being trimmed or rounded.

Similar letters of reference designate corresponding parts in all the iigures.

A designates the frame of the machine. It may be of any suitable construction and made of any desirable material.

B designates a support for abat-body to be trimmed. As here shown,this support con-A sists of four arms b b2 b3 b4, which at the upper ends are provided with segmental plates l), which are adapted to together support a hat-body by fitting around the crown and affording a rest for that portion of the brim, which is immediately adjacent to the crown. It will'be seen by reference to Fig. 3 that the segmental pieces of the arms b b3 are of a shorter or more abrupt curve than the segmental pieces of the arms b2 b4, and that,

therefore, these segmental pieces together conform quite well to the shape of an ordinary hat-body.

i The :arms b b2 b3 if* are connected at the lower ends with blocks b5, which are iitted in slideways formed in the block 196, so as to be capable of moving toward and away from a common center. These blocks b5 are severally made of two sections l and 2, the former of which is fitted to slide longitudinally upon the other. A screw 3 is combined with the two sections l 2 of each bloc-k h5. The construction of one of the blocks and the engagement of the screw with its two sections is well illustrated in Fig. 2. By thus forming the blocks of adjustable sections, we provide for setting the arms b' b2 h3 b4 at different distances from the common center toward and away from which they may be adjusted by means of adjusting the blocks b5,which carry them. All the blocks h5 engage with a block 67, which rotates about the common center relative to which the blocks are capable of adjustment, and is provided 0n its upper face with a scroll-shaped or spiral thread, which engages with threaded segments on the ad jacent portions of the sections 2 of the blocks b5, so that by rotating this block bi the blocks b5 may together be adjusted outwardly or inwardly. Thus provision is aftorded' for adjusting the segmental pieces b to adapt them to hold hats of different sizes. IE it should become desirable to adjust these segmental pieces for hats of different shape, the screws 3 of one or more of the blocks b5 would have to be manipulated. As shown, the ends of the screws 3 are made of polygonal form, so that a wrench may be engaged with them when it is necessary to rotate them for the purpose of changing the relation between the sections of the blocks b5, and to provide for an adjustment of the rotary block bf. The latter is provided with a number of handles hs, which extend downwardly from the block and thence radially outward. Ve prefer to provide the block with a number of these handles bs, so that the blocks may be manipu lated from a number of points in their circumference. j

We prefer to combine with the body piece IOO or block bo and one of its blocks b5 a scale and index, whereby the blocks b5 can be adj usted to different sizes of hat-bodies and it may be determined whether hat-bodies subjected to treatment in themachine are of the standard size. /Ve have shown a scale Zr arranged on the upper side of the body piece or block Z9 and an index or pointer bw fastened to the side of one of the blocks b5 to travel over the scale, as may be best understood from Figs. l to 3. The body piece or block h6 has a central hub projecting from its under side. A ring b is screwed upon the outside of this hub. Below this ring and the hub a ring i912 is arranged. This ringjis secured by screws Z913 with the body piece or block b, and hence is incapable of independent movement.

The ring Z912 is to be connected to a shaft C. The shaft C therefore carries the hat-support, consisting of the segment-pieces h. It serves to rotate the hat-bodies in such a manner as to connect the brim requiring trimming to rotary cutters D D2.

The shaft C is journaled in a bearing a provided in a cross-piece or bed a', which is comprised in the machine-frame A. lt has affixed to its lower end a gear-wheel c, which meshes with a gear-wheel c affixed to a stud c2, which is supported bythe frame A. A bevel gearwheel c3 is affixed to the gear-wheel c and engages with a bevel gear-wheel c4, which is loosely mounted upon shaft E.

The shaft E is secured in the frame A ot' 'the machine. It is not intended to rotate. On it are loosely mounted a iiy-wheel e, a beltpulley e', and a driving-belt pulley e2. The iiy-wheel and the two belt-pulleys are locked together by cross-pins which rotate in unison. The belt which is 'Fitted to the driving-pulley e2 transmits to the machine power from any source. The belt-pulley e transmits power through abelt e3 to a belt-pulley f, affixed to a counter-shaft F.

The machine is intended to cause but a single rotation of the hat-bod y and then stop. To enable it to do this we combine with the beltpulley e2 and the bevel gear-wheelc4 aclutch, and also combine with the latter a stop whereby the operation ot the machine will be terminated periodically. The clutch consists of anumber of pins e4,which are tted in cavities formed in the driving-belt pulley @2in positions parallel with the axis of the latter. These pins e4 are shouldered. Their larger ends project from the pulley e2 toward the bevel gear-wheeler, while their smaller ends extend lthrough the backs of the cavities in the pulley e2, which accommodate them and are furnished beyond the back of said cavities with cross-pins, whereby they are prevented from becoming detached from the pulley. Ooiled springs surrounding the smaller portions of the pins e4 and within the cavities in t-he pulley 62 tend to force the pins e'1 toward the bevel gear-wheel c4. The bevel gear-wheel c4 is provided with a cavity, in which a pin c5 is iitted in a position parallel with the axis of the wheel and at suoli a distance from the axis that this pin may engage with one of the pins e* of the pulley e2. The pin c5 is forced toward the frame ot the machine by means of a spring which is coiled around it and is designed to have a bearing at one end against the bevel-wheel c* and at the other end against a head with which the pin is provided.

ln the machin e-frame is a recess, into which the head of the pin c5 may be forced by the spring. When the pin is forced into this recess, the gear-wheel c* will be locked to the frame and the machine stopped. Once in each rotation of the bevel gear-wheel this will occur. lVhen the pin c5 is moved longitudinally to disengage ittrom the frame A, it will project into the path of the pins e4, and the iirst one of these pins e4 which reaches it will transmit motion through it to the bevel gearwheel c4, and in this way the machine will operate. its recess in the frame it Will move longitudinally outof engagement with that one of the pins e4 with which it was previously engaged. l-Ience'it will no longer be in condition to derive motion from the driving-belt pulley e2,and will, moreover, be stopped by engagement with the frame A.

E is a lever fulcrumed at e5 to the cross piece or bed a of the machine-frame. At one end it is bent to extend into the recess which is provided in the machine-frame for the reception of the pin c5. This end is moved outwardly away from the recess by a spring e, as far as it is permitted to move by a stoppin e7, which is inserted in the cross piece or bed a. The other end ot this lever is provided with a handle and extends into a position convenient for the operator of the machine. When this lever is oscillated against the resistance of the spring e6, it may be made to force the pin c5 out of its recess in the machine-trame A and into the path of one of the pins e4. The advantage of providing a number of pins e4 is so that the driving-pulley e2 may more readily engage with the bevel gear-wheel c4. A yielding connection between the pins e4 and the driving-belt pulley e2 is advantageous, because if the lever Eshould force the pin c5 toward the driving-belt pulley e2 when one of the pins e4 happens to be opposite said pin c5 breakage will be obviated by the longitudinal yielding of the pin e4, and afterthat the next pin e4 will engage with the pin c".

J designates a device termed a holddown, whose function is to secure a hat-body in the hat-holder B. This consists, essentially, of a body-piece j, which may advantageously be made of oval form and a number of adjustable arms j iitted to said body. These arms j are fitted into radial notches in the body j and provided with sockets in which helical springs `7'2 are arranged. These springs bear at one end against the extremities of the sockets of the arms j and at the other end against the backs ol' the notches in the As soon as the pin ccomes opposite IOC IIO

body j; hence they tend to force the arms outward. Stop-pins jg, inserted in the body and in position to cross lugs jt, with which the arms at their inner ends are provided, limit the outward movement of the arms. This hold-down J is fitted to a stud ,75, which is secured to a slide K. The slide K works vertically in the slideway formed in the machine-frame. lVhen it is lowered, the holddown is brought into contact with a hat-body in the hat-holder and serves to secure it in place. The arms j at their outer ends have downward extensions, which are inclined at their lower extremities, so that when they are lowered they may wedge themselves into a hat-body. Above the inclines are lugs j, which will bear against that portion ot' the brim of a hat-body which is contiguous to the crown. It will be readily understood that the hold-down acts with a yielding pressure to clamp a hat-body in the hat-holder. NVhen the hold-down has secured a hat-body in the holder, it may rotate with the hat-holder and hat-body by turning about the stud The slide K is counterbalanced. In the present instance its counter-balance consists of a weight k, attached to one end of a cord or like device It', which passes around guidepulleys k2 k3, which are mounted upon the machine-frame and is fasten ed to the slide K. The upward movement of the slide under the influence of the counter-balance is limited by a stop-pin 7cm, inserted in the machine-frame. Q

The lever G, previously mentioned, is longitudinally slotted near one end to receive a pin 7a4, extending horizontally from the slide K. A cord, chain, or like device g is connected to the lever G, passes thence around guide-pulleys g 92- g3 g4, mounted on studs supported by the machine-frame, and is fastened to a treadle or lever L, which is fulcrumed to the machine-frame by a pin Z.

The end of the lever G, which is connectedto the slide K, projects so far forward or to one side of the slide K that in descending it will impinge against the lever D3 and move the latter downward.

The attendant of the machine will, after inserting a hat-body in the holder B, depress the treadle L, and so lower the hold-down .l and the upper critter D2. Having done this, he will manipulate the lever l so as to unlock the bevel gear-wheel c4 from the machineframe and interlock it with the driving-belt pulley e2. This will cause the hat-holder to make one complete rotation and at the end of its rotation the machine will automatically come to rest. If then the attendant releases the pressure upon the hold-down, the latter will rise.

Having now described the adjustability of the holder for the hat-bodies and the means of rotating the same, we will take up the cutters D D2. These are supported in a frame D. The lower cutter D" is mounted upon a vof an operative position.

shaft d', which is journaled'in a iixed position in the frame D. The upper cutter D2 is mounted upon a shaft d2, which is journaled in a bearing-box d3, which is capable of sliding vertically in one of the arms of the frame D. Springs di, located between the upper extremities of the arm j ust mentioned and laterally-extending lugs d5, with which the bearing-box for the shaft d2 is provided, move the bearing-box upwardly when this is possible and hold it and the shaft d2 in an elevated position with the cutter D2 out of operation. Pins d limit the upward movement of the bearing-box cl3 and pins d7 limit its downward movement. It is depressed by a lever D3, which is fulcrumed by a pin cls to one of the arms of the frame D and extends thence over the top of the bearing-box d3. Preferably a roller C19 will be journaled to the bearing-box beneath the lever D3. The leverD3 is swung downwardly by a lever G, presently to be described. It will. be swung upward'by the springs d4. The frame D is pivotally connected by a pin or screw d10 to a slide-piece D4. Hence it may be rotated or oscillated at any time upon this pin. d10 as a center to swing the cutters D D2 and the lever D3 out We have shown a screw-pin d10, and this is advantageous because it may be made to clamp the frame D in any position to insure the stability of the frame D. Vhen in its operative position, we may provide it and the slide-piece D4 with lugs d20 d21 and t a screw Z22 into the same.

The shaft d of the lower cutter D has affixed to it a belt-pulley du. A belt C112 passes around the same and also around a pulley d, which is made suficientlywide to permit of the travelof the belt in the direction of .its

vaxis to allow of adjustingthe cutters nearer to or farther from the hat-holder. The pulley d is on the counter-shaft F, previously referred to, and therefore is continuously driven from the belt-pulley e.

On the shaft d of the lower cutter a gearwheel d1l is affixed. This wheel engages with a gear-wheel C119, which is affixed to the shaft d2 of the upper cutter. Consequently when the shaft d2 is lowered to adjust the upperk cutter to an operative position the shaft (Z2 of this cutter will be rotated.

To provide for securing a proper alignment of the cutters, wev support the shaft d so that it can have a longitudinal adjustmentf Its movement is precluded in one direction by the impingement of the inner end of the body of the cutter against the bearing-box in which the outer end of the shaft is journaled. Its movement in the other direction is resisted by means of a spring dl. This spring is shown as consisting of a block of india-rubber fitted in a box C116, which abuts against one end of the bearingbox last mentioned. The gear-wheel d14 is secured to the shaft d just in rear of the spring dw. Obviously the shaft d may move longitudinally in one di- IOO IIO

rection by pressing the spring and will be moved in the reverse direction by the action of the spring.

Afxed to the shaft CZ of the lower cutter is `a disk d, and on the shaft (Z2 of the upper cutter is affixed a cam (PS, which has a rounded surface that is adapted on the descent of the shaft cl2 to contact with the disk d to force the shaft d forwardly, or, in other words, toward the hat-holder. By this combination of parts we provide for adjusting the cutters into proper relation with each other during the time they are used.

The slide D4 is fitted to a slide D5 and the slide D5 is fitted to a slide DG. Each one of these slides is capable of movement toward and from the hat-holder. The slide D5 is also capable of movement in these directions independently of the slide D5, and the slide D4 is capable of a similar movement independently of the slide D5, as well as of the slide D5. The slide DGhas a horizontally-extending portion and a downwardly-extending portion. The horizontally-extending portion is provided on the under side with rollers CFS, which are fitted to studs extending from lugs formed with the slide and travel along rails or ledges CX24, with which the machine-frame is provided.

The downwardly-extending portion of the slide D5 is preferably provided with a roller e125, which bears against a cam H. This cam may advantageously be made of wood. It is mounted upon a shaft I, which is arranged in line with the shaft C and derives rotary inotion from the latter. The cam H is to have the same outline as that to which the brims of hat-bodies are to be trimmed, although it need not be of the same size as the edge of the brims when trimmed. As this cam rotates it moves the slide D5, and consequently the slides D5D4and cutter-carrying frame D relatively to the center of the hat-holder. As shown, it only moves these parts outwardly, and a spring D7, which, as here shown, acts against the slide D5 and moves them inwardly. This spring, as shown, at one end surrounds a pin that projects outwardly from the horizontal portion of the slide DG and extends into a pocket d2, with which the machine-frame is provided. The spring bears against a plate which is attached to a screw d, that is longitudinally adjustable in the pocket. Hence by manipulating this screw the tension of the spring may be varied. The pocket, as here shown, is made integral with a bracket, which is fastened to the machine-frame.

Obviously different hat-bodies will require cams H of diierent shape, and owing to this we provide for readily substituting one such cam for another. A simple way of affording this provision consists in constructing the upper end of the shaft Ito interlock with the lower end of the shaft C, and so supporting the shaft I that it may he moved vertically to disengage it from and re-cngage it with the shaft C. The shaftI has its upper end made frame.

polygonal, and the shaft C is provided with a socket capable of engaging with the polygonal end of the shaft I. This socket is not in the present instance formed in the shaft C, but consists of a collar G, which is attached to the shaft C. This collar is shown as fastcned to the shaft C indirectly by being secured through the agency of screws to the gear-wheel c, which is secured to the said shaft.

The shaft I is supported in a bearing I', which is provided in a cross-piece of the machine-frame, and at the lower extremity has a step-bearing in a sleeve I2, that is pivotally connected bya pin with a ,lever I3. This lever I3 is fulcrurned by a pin 'i' to a bracket i2, secured to a cross-piece of the machine- Between the ends it is slitted or bifurcated to embrace the sleeve I2, and this portion is connected by the pin z'to said sleeve. The other end of the lever I3 has a handle, whereby it may be swung up and down to raise and lower the shaft I. This end of the lever may by a slight lateral movement be engaged with and disengaged from a hook 3, which is fastened to the machine frame. When the lever is engaged with this hook, it will support the shaft I in aposition to maintain engagement with the shaft C. After the disengagement of the lever from the hook the lever may be lowered to disengage the shaft I from the shaft C. After this the cam H may be lifted off the polygonal end of the shaft I, with which it interlocks, and it may be replaced by a different cam, after which the shaft I will be elevated again to engage with the shaft C.

The slide D5 is preferably made to form a double dovetail to engage with both the slide DG and the slide D4. A screw d5* passes through a slot that extends lengthwise of the horizontal portion of the slide D5 and engages with a tapped hole in the slide D5. This screw is provided with acollar of sufficient size to eX- tend across the said slide. Hence by turning thezscrew it may be made to clamp the slides D5 D6 together.

The slide D4 has a horizontal portion,which is provided with a slot that is elongated toward the hat-holder. Through this slot passes a screw e129, which engages with a tapped hole in the slide D5. The screw d5 has a head which bridges across the said slot. Hence by turning the screw the slides D4 D5 may be clamped together.

The slide D5 is provided with an arm d50, which is preferably furnished with an antifriction roller dsl. Normally the arms b b2 b5 b4 of the hat-holder occupy such positions that the arms b will be opposite the roller C131 ofthe slide D5. Vhen the arms of the hat-holder are adjusted, the arm b will therefore adjust the slide D5 to the proper position to suit the size of hat-body for which the adjustment of the hat-holder was made. This adjustment would adjust the cutters properly if the hatbodies of the size for which the adjustment IOO IIO

of the holder was made had to be trimmed to project the same extent from the hat-body. If, however, the brims of the hat-bodies were trimmed so as to be broader or narrower, an adjustment of the slide D4 relatively to the slide D5 would have to be made. To facilitate this adjustment for the project-ion of a brim of any desired width, we preferably combine with the slides D4 D5 ascale and index di?. The scale is here shown as fastened to the slide D4 and the index is made in the form of a rod screwed into the slide D5 and working through a notch in one edge of the slide DL.

It is obvious that the outward movement of the slide D5 is produced by the scroll or cam if, whereby the corresponding movement of the hat-holder arms is produced, and that the reverse movement of said slide is produced by the spring D7. f

`vAn adjustment between the slides D6 D5 provides for the use of a cam of a different shape as distinguished from one merely of a larger size, corresponding to the size to which the hat-holder was adjusted.

Mdesignates achalk-holder.l As here shown, it consists of a lever fulcrumed by a pin m to the machine-frame and having a socket m', which holds a piece of chalk. By oscillating the lever the chalk may be brought in Contact with the under side of the brim of ahat-body. The socket for the chalk has preferably combined with it a screw m3, which may serve to cause the chalk to project more or less. Normally the lever of the chalk-holder rests upon a stop-pin m2. The socket m of the chalkholder is shown as formed with a plate m, which has a sliding connection with the lever M. In this way the chalk may be adjusted to act on the brim nearer to or farther from the crown. If the cross-pin m2 were elevated a little, so as to move the lever Minto a horizontal position, the sliding section m4 could be moved lengthwise to mark upon the lower end of the under side of the brim without any operation of the lever M. In this case the lever would have to be shortened at the end which is the nearer to thehat-holder, so as to allow of the adjustment of the chalk beyond the circumference of the brim.
